What the car is and where it came from
The Citroën C6 is an executive saloon launched in November 2005. It was designed by Jean-Pierre Ploué’s team to replace the XM, six years after the XM ceased production in June 2000. It draws directly from the C6 Lignage concept shown at Geneva in spring 1999.
How it works, in terms someone would actually use
The C6 uses Hydractive 3+ suspension to isolate the cabin from road texture. It projects speed and navigation onto the windscreen via heads-up display. The bonnet lifts automatically in a collision to cushion pedestrian impact.
What it gets right
It delivers a fastback-saloon silhouette rooted in the 1999 C6 Lignage concept. It integrates advanced driver aids without cluttering the cabin. It signals intent: Citroën was no longer designing for cost alone.
What it does not
It does not replace the XM’s cult status. It does not achieve volume: only 23,384 units were built between 2005 and 2012. It does not establish a new executive segment for Citroën in Europe.
What it changed
It marked Citroën’s pivot from idiosyncratic engineering (XM) to design-led brand rejuvenation under Ploué—prioritising silhouette, presence, and tech over mechanical novelty.
Who it is for, and who it is not
It is for buyers who value avant-garde form and French technical ambition in a large saloon—but not those seeking resale value, dealer network depth, or benchmark ride refinement.
Is it worth your time
Yes—if you want to understand how Citroën tried, and failed, to reposition itself as a premium saloon maker in the mid-2000s.
